A full-length cDNA of metallothionein, designated PaMT, was cloned from SSH libraries. PaMT consists of 141 bp that code 46 amino acids. Classic structure (cxc) of metallothionein and the phylogenetic tree analysis show that PaMT belongs to metallothionein family. PaMT is preferentially expressed in root and its expression is strongly up-regulated by heavy metal stress. PaMT-NusA fusion protein expressed in Coli BL21 plays a role in the tolerance to heavy metal toxicity.
